Why is it that for some strange reason the subject matter of this story does not surprise me one iota?

A Democratic assemblyman is in jail, arrested for threatening Democratic Speaker-elect Marilyn Kirkpatrick, according to North Las Vegas Police and Democratic sources familiar with the situation.

Assemblyman Steven Brooks, 40, of North Las Vegas made threats to harm a public official Saturday afternoon, police said in a news release Sunday morning. A source said he was arrested with a loaded gun after threatening to shoot Kirkpatrick.

Kirkpatrick and witnesses who corroborated the allegation prompted police to begin searching for Brooks. About 5:30 p.m., Brooks was seen driving in the area of Carey Avenue and Mt. Hood Street, where he was taken into custody without incident during a traffic stop.

Another Democratic source with knowledge of the situation said Brooks publicly threatened to harm Kirkpatrick because he was unhappy with the committee assignments given to him by Kirkpatrick. The 2013 Legislature begins Feb. 4.

Kirkpatrick was selected to lead the Assembly by the Democratic caucus, but she was expected to face divisions. Her caucus was split between her and Assemblyman William Horne, D-Las Vegas, after the presumed incoming speaker, Assemblyman Marcus Conklin, D-Las Vegas, lost his re-election bid. That threw the caucus into turmoil.

Brooks had told lobbyists and other lawmakers that he had expected to become chairman of the Assembly Ways and Means Committee, a powerful committee that oversees changes to the governor’s proposed budget. Assemblywoman Maggie Carlton, D-Las Vegas, was selected for the position.

Brooks was booked into Las Vegas City Jail on one count of intimidating a public officer by threat of physical violence.

North Las Vegas Police, citing the ongoing investigation, would not release further details.

A politician furious at a fellow politician posing a threat with a gun? It should be taken seriously not just because of the current climate, but because of THIS SAD CHAPTER in American political history.
